What is RUP?
Iterativesoftware development process
framework created by the Rational Software
Adaptable process framework , intended to be tailored by the development organizations and software project teams that will select the elements of the process that are appropriate for their needs.
It combines the experience base of companies to articulate 6 best practices: iterative development requirements management employment of a component-based architecture modeling software visually
Continuous verification of quality
Control change control.
Tailorable process that guides development, has tools that automate that application, & services that accelerate the adoption of those processes & tools.
Capability Patterns-Add/Remove chunks of Processes + Modify to address needs.
Ready to use Delivery Processes-quick starting point for planning & initiating a project.

Invented by Ivar Jacobson, Grady Booch & James Rumbaugh.

Architecture Centric with 4+1 Views of an architecture:
Logical: the functionality as seen by the end user
Implementation: the system as seen by the programmers
Process: view seen by system integrators
Deployment: view seen by system engineering to be used for installation and delivery
Use-Case: the high level use-cases that drive the architecture
Supported by tools

The RUP uses four elements to describe processes:
Workers – describe a role, some people have many roles.
Activities – small, definable, reusable tasks that can be allocated to a single worker.
Artifacts – usually process deliverables, like: use cases, code, plans, test cases, test results.
Workflows – coordinated sequences of activities.
There are 9 workflows, 6 engineering workflows:
Business modeling, Requirements, Development & Analysis,
Implementation. Test, Deployment.
And 3 supporting workflows:
Project management, Configuration and Change Management,

Kruchten gives the following proportions as typical: Inception 10%, Elaboration 30%,
Construction 50%, Transition 10%.

Analysis & Design
Configuration & Change
Document business processes using business use cases.
Describe what a system should do (elicit, organize, document required functionality, constraints, track & document trade-offs & decisions).
System will be realized in implementation phase.
To define organization of code(subsystems), implement classes & objects(components), test components as units, integrate results from implementers/teams into an executable system.
Verify interaction between objects, integration of components, requirements have been correctly implemented, identify & ensure defects are addressed prior to deployment.
Producing external releases, packaging, distributing, installing, providing help & assistance to users.
Framework for managing software intensive projects, practical guidelines for staffing, executing & monitoring projects, manage risk.
Manage multiple variants of evolving software systems, tracking versions, performing builds, enforcing site-specific development policies, perform change request management.
Provide software development organization with software development environment - processes + tools to support the development Team.

RUP is like an online mentor that provides guidelines, templates, and examples for all aspects and stages of program development.
The RUP development methodology provides a structured way for companies to envision & create software programs.

OpenUP(OpenUP): is a part of the Eclipse Process Framework source process framework developed within the
Eclipse Foundation open
. Its goals are to make it easy to adopt the core of the RUP / Unified Process .
Agile UP: simplified version of the IBM Rational Unified Process developed by Scott Ambler .
The AUP applies agile techniques including test driven development (TDD), Agile Modeling , agile change management, and database refactoring to improve productivity.
EssUP: you can pick those practices that are applicable to your situation and combine them into your own process.
UPEDU: software development process specialized for education , developed by
Pierre-N. Robillard (École Polytechnique de Montréal), Philippe Kruchten
(Rational Software) and Patrick d'Astous (École Polytechnique de Montréal).
ITUP: knowledge base of widely accepted industry best practices and the accumulated experience from IBM 's client engagements.
Oracle Unified Method: plan-based method – that includes extensive overview material, task and artifact descriptions, and associated templates – the method is intended to be tailored to support the appropriate level of ceremony required for each project which is used by Oracle employees, customers & partner networks.

This is a complete methodology in itself with an emphasis on accurate documentation
It is proactively able to resolve the project risks associated with the client's evolving requirements requiring careful change request management
Less time is required for integration as the process of integration goes on throughout the software development life cycle .
The development time required is less due to reuse of components.
There is online training and tutorial available for this process.

The team members need to be expert in their field to develop a software under this methodology.
The development process is too complex and disorganized.
On cutting edge projects which utilise new technology, the reuse of components will not be possible. Hence the time saving one could have made will be impossible to fulfill.
Integration throughout the process of software development , in theory sounds a good thing. But on particularly big projects with multiple development streams it will only add to the confusion and cause more issues during the stages of testing

The iterative Phases of RUP find application in ICSM Spiral Model Life-Cycle phases & milestones.
The core workflows of RUP are incorporated as activities in ICSM.
The management workflows (PM,CCM & ENV) of RUP could be incorporated in
The RUP related frameworks could be adopted for a particular project (domain) that plans to use ICSM.
The Best Practices upon which RUP was built are now the pillars on which ICSM rest.

By incorporating many more features of RUP, ICSM can be tailored to be a better process to design Software & Systems.
